HELP!! Is my egg alive?

[newegg24601]

I’m very new to egg incubating and I’m not sure if my egg is alive. I have a singular duck egg and I’m not sure how far along it is or if it is even alive. Most of it is dark when I candle it but there’s some red/orangey parts as well as vague veins. There’s also an air sac and I think there’s bruising too but I’m so new to it that I don’t know what is happening.
